Description

Technical Field

[0001] This utility model relates to the field of bridge deflection monitoring technology, and in particular to a real-time bridge deflection monitoring device. Background Technology

[0002] During use, bridges are affected by traffic loads, climate change, and earthquakes, leading to structural deformation and deflection changes. Real-time monitoring equipment can continuously track these changes, promptly identify potential structural problems, and ensure the safety and stability of the bridge. By monitoring bridge deflection in real time, it is possible to determine the bridge's response under different working conditions, helping observers assess the bridge's safety and service life, thereby preventing potential safety hazards. The monitoring equipment includes a 3D laser scanner, which uses laser scanning to quickly and accurately measure bridge deflection changes, especially the dynamic response under load and temperature changes.

[0003] When a 3D laser scanner is working, observers need to make multiple observations to obtain more accurate data, which helps to reduce random errors and improve measurement accuracy. Bridge structures are affected by loads and climate changes during use, and repeated observations can track these changes in real time. However, observers need to stare at the front of the scanner for a long time without support, which can lead to blurred vision and inaccurate judgment of the equipment readings. Due to the lack of sufficient support, observers need to frequently adjust their body position, which increases the possibility of operational errors. Therefore, a real-time bridge deflection monitoring device was designed. Utility Model Content

[0004] The purpose of this invention is to provide a real-time bridge deflection monitoring device to solve the problems mentioned in the background art, such as the inability to accurately judge the device readings due to prolonged posture without support, and the need for observers to frequently adjust their position due to insufficient support, which increases the possibility of operational errors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a real-time bridge deflection monitoring device, comprising a monitoring instrument body and a tripod. The tripod is located at the bottom of the monitoring instrument body. Arc-shaped frames are provided on both sides of the monitoring instrument body. Movable blocks are provided inside the two arc-shaped frames. A support plate is provided on one side of the monitoring instrument body. Two support frames are provided on the top of the support plate. A support bracket is provided between the inner walls of the two support frames. A soft pad is provided on the top of the support bracket. Multiple sweat-wicking holes are opened on the surface of the soft pad. A moisture-absorbing pad is filled on the top of the support bracket.

[0006] As a preferred technical solution of this utility model, one side of each of the two arc-shaped frames is fixedly connected to both sides of the monitoring instrument body, and a fixing rod is fixedly installed inside each of the two arc-shaped frames.

[0007] As a preferred embodiment of this utility model, the two movable blocks are respectively movably sleeved on one end of the two fixed rods, and a movable plate is fixedly installed on one side of each of the two movable blocks.

[0008] As a preferred embodiment of this utility model, the top of the support plate is fixedly connected to the bottom of the two movable plates respectively, and a reinforcing block is fixedly installed on the top of each of the two movable plates. A support shaft is inserted and connected to one side of each of the two reinforcing blocks.

[0009] As a preferred embodiment of this utility model, a reinforcing plate is sleeved on one end of each of the two supporting shafts, and an L-shaped plate is provided on one side of each of the two reinforcing plates.

[0010] As a preferred embodiment of this utility model, each of the two L-shaped plates is connected to a pressure rib on one side, and one end of each pressure rib is fixedly connected to the bottom of the support bracket.

[0011] As a preferred embodiment of this invention, the two sides of the two soft pads are respectively bonded to one side of the two support frames.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention incorporates a fixed rod, movable blocks, a support plate, a support bracket, a soft pad, sweat-wicking holes, and a moisture-absorbing pad. Two movable blocks move back and forth at one end of the fixed rod, allowing adjustment of the positions of the support plate and support bracket. The observer's chin contacts the soft pad, which provides support. The soft pad is made of polyurethane, offering flexibility and comfort, effectively distributing pressure, minimizing skin irritation, and reducing the burden on the observer's neck from constant suspension. Sweat permeates through multiple sweat-wicking holes to the surface of the moisture-absorbing pad. Made of polyester fiber, the pad is absorbent and breathable, absorbing the sweat. The moisture-absorbing pad can be removed from between the support bracket and the soft pad for easy replacement. This design solves the problem of insufficient support for monitoring equipment, requiring frequent adjustments to the observer's position and reducing the risk of operational errors.

[0014] This utility model incorporates a movable plate, a support shaft, a reinforcing plate, an L-shaped plate, and pressure ribs. The friction between the movable block and the fixed rod is high, so the movable block will remain stationary at one end of the fixed rod when no pressure is applied to the support plate. The support shaft and the L-shaped plate are fixed together by the reinforcing plate, and one end of the pressure rib is connected to the bottom of the support bracket. This enhances the support strength of the pressure rib on the bottom of the support bracket, making it more stable. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution for a real-time bridge deflection monitoring device:

[0022] Example 1:

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a bridge deflection real-time monitoring device includes a monitoring instrument body 1 and a tripod 2. The tripod 2 is located at the bottom of the monitoring instrument body 1. Arc-shaped frames 3 are provided on both sides of the monitoring instrument body 1. Movable blocks 5 are installed inside each of the two arc-shaped frames 3. A support plate 7 is provided on one side of the monitoring instrument body 1. Two support frames 13 are provided on the top of the support plate 7. A support bracket 14 is provided between the inner walls of the two support frames 13. A soft pad 15 is provided on the top of the support bracket 14. Multiple sweat-wicking holes 16 are formed on the surface of the soft pad 15. A moisture-absorbing pad 17 is filled on the top of the support bracket 14. Two movable blocks 5 are movably fitted onto one end of two fixed rods 4 respectively. A movable plate 6 is fixedly installed on one side of each of the two movable blocks 5. Sweat permeates through multiple sweat vents 16 to the surface of the moisture-absorbing pad 17. Since the moisture-absorbing pad 17 is made of polyester fiber, it has moisture absorption and breathability. Therefore, the sweat will be absorbed by the moisture-absorbing pad 17. The moisture-absorbing pad 17 can be pulled out from between the support bracket 14 and the soft pad 15, so that the soaked moisture-absorbing pad 17 can be replaced. This solves the problem that the monitoring equipment lacks sufficient support and the observer needs to frequently adjust his body position, reducing the risk of operational errors.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4 As shown, the top of the support plate 7 is fixedly connected to the bottom of the two movable plates 6 respectively. The top of each of the two movable plates 6 is fixedly installed with a reinforcing block 8. A support shaft 9 is inserted through one side of each of the two reinforcing blocks 8. A reinforcing plate 10 is sleeved on one end of each of the two support shafts 9. An L-shaped plate 11 is provided on one side of each of the two reinforcing plates 10. A pressure rib 12 is inserted through one side of each of the two L-shaped plates 11. One end of each pressure rib 12 is fixedly connected to the bottom of the support bracket 14. The friction between the movable block 5 and the fixed rod 4 is large. When no pressure is applied to the support plate 7, the movable block 5 will remain stationary at one end of the fixed rod 4. The support shaft 9 and the L-shaped plate 11 are fixed together by the reinforcing plate 10. One end of the pressure rib 12 is connected to the bottom of the support bracket 14.

[0026] Working Principle: During use, bridges are affected by traffic loads, climate change, and earthquakes, leading to structural deformation and deflection changes. Real-time monitoring equipment can continuously track these changes, promptly identify potential structural problems, and ensure the safety and stability of the bridge. By monitoring bridge deflection in real time, the bridge's response under different working conditions can be determined, helping observers assess the bridge's safety and service life, thereby preventing potential safety hazards. The monitoring equipment includes a 3D laser scanner. Using laser scanning, it can quickly and accurately measure bridge deflection changes, especially the dynamic response under load and temperature changes. When the 3D laser scanner is working, observers need to make multiple observations to obtain more accurate data, which helps reduce random errors and improve measurement accuracy. Bridge structures are affected by loads and climate change during use, and repeated observations can track these changes in real time. However, observers need to stare at the front of the scanner for a long time without support, which can lead to blurred vision and inaccurate interpretation of the equipment's readings. Due to the lack of sufficient support, observers need to frequently adjust their posture, increasing the possibility of operational errors. Therefore, a real-time bridge deflection monitoring device is designed, in which two moving blocks 5 move back and forth at one end of a fixed rod 4, thereby... By adjusting the positions of the support plate 7 and the support bracket 14, the observer's chin contacts the soft pad 15, which supports the chin. The soft pad 15 is made of polyurethane material, which is flexible and comfortable, effectively distributing pressure and is less likely to irritate the skin. This reduces the burden on the observer's neck, which is constantly suspended. Sweat permeates through multiple pores 16 to the surface of the moisture-absorbing pad 17. Since the moisture-absorbing pad 17 is made of polyester fiber, it is absorbent and breathable, so the sweat is absorbed by the moisture-absorbing pad 17. The moisture-absorbing pad 17 can be pulled out from between the support bracket 14 and the soft pad 15, allowing for replacement of the soaked moisture-absorbing pad 17. This solves the problem of insufficient support for the monitoring equipment. The problem of observers needing to frequently adjust their positions is reduced, thus minimizing the risk of operational errors. The friction between the moving block 5 and the fixed rod 4 is high, so the moving block 5 will remain stationary at one end of the fixed rod 4 when no pressure is applied to the support plate 7. The support shaft 9 is fixed to the L-shaped plate 11 by the reinforcing plate 10. One end of the pressure rib 12 is connected to the bottom of the support bracket 14, thus enhancing the support strength of the pressure rib 12 on the bottom of the support bracket 14 and making it more stable. The bottoms of the two support frames 13 are respectively fixed to one side of the two reinforcing plates 10. The combined use of the reinforcing block 8, the support shaft 9, and the reinforcing plate 10 enhances the support strength of the L-shaped plate 11.
